SI53154-A01AGMR

Overview

The SI53154-A01AGMR is a four-port PCIe clock buffer compliant with Gen 1, Gen 2, Gen 3, and Gen 4 standards. It operates within a frequency range of 100 MHz to 210 MHz using a 3.3 V power supply (3.135 V to 3.465 V). The device features low-power push-pull differential outputs with internal termination. Key electrical parameters include an additive PCIe Gen 2 phase jitter of 0.5 ps RMS, Gen 3 jitter of 0.10 ps RMS, and Gen 4 jitter of 0.10 ps RMS. It supports spread spectrum inputs and includes dedicated hardware output enable pins alongside I2C programmability for dynamic control.

Feature Summary

• Four differential PCIe clock outputs supporting Gen 1 through Gen 4 standards
• I2C interface for programmable skew, edge rate, and amplitude adjustment
• Dedicated active-high OE pins for synchronous start/stop of individual outputs
• Spread spectrum tolerant input with LVDS output support

Applications

• PCI-Express common clock systems
• Network attached storage
• Wireless access points
• Routers

Procurement Notes

Verify the 'R' suffix indicates tape and reel packaging rather than tray packaging when sourcing components. Confirm the extended temperature rating (-40 °C to 85 °C) matches system requirements. Ensure the 24-pin QFN land pattern adheres to IPC-7351 guidelines during PCB design.

Selection Notes

Select this component for designs requiring simultaneous buffering of four PCIe clocks with low additive jitter. The I2C capability allows for dynamic signal integrity optimization. Verify that the input frequency falls between 100 MHz and 210 MHz. Consider the -40 °C to 85 °C operating range for industrial environments.

Part Context

This part belongs to the Si53154 family of quad fanout buffers manufactured by Skyworks Solutions. It serves as a direct replacement for similar PCIe clock distribution devices in high-speed serial link architectures. The 'A01AGM' variant shares identical electrical specifications but utilizes tray packaging instead of tape and reel.
